i have 2 similar projects(FastAPI, redis, postgres) with same Dockerfile:

FROM python:3.14.2-slim

WORKDIR /myapp

COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

COPY . .
ENV PYTHONPATH=/myapp

First one works well, but second crashes with(API):

ImportError: cannot import name 'AskError' from 'redis.exceptions' (/usr/local/lib/python3.14/site-packages/redis/exceptions.py).

I know the cause, for some reason: there is redis 2.0.0 in site-packages folder(in working project everyrhing is fine and it's actually 7.1.0 version), but in both projects there is:

redis==7.1.0

I tried:

• enter the docker container and run: pip show redis (it says 7.1.0 version)

• then I went to /usr/local/lib/python3.14/site-packages/redis/ and i see in __init__.py the line __version__ = 2.0.0 (WHY!?!?!).

• Obviously the exceptions.py file does not have AskError exception class

• Also i tried to put this in dockerfile:

FROM python:3.14.2-slim

WORKDIR /myapp

RUN pip install --upgrade pip && \
    pip uninstall -y redis && \
    rm -rf /usr/local/lib/python*/site-packages/redis*
